In this paper, the authors study GRMS, a global scheduling scheme for rate monotonic tasks on a multiprocessor. Several admission control algorithms for GRMS are presented, both for hard and soft real-time tasks. The average performance of these admission control algorithms is compared with the performance of known partitioning schemes. The result of these comparisons outlines some situations where one scheme is preferable over the other. Partitioning schemes are better suited for hard real-time systems, while a global scheme is preferable for soft real-time systems.
